Flexit Nordic KS3 is a compact ventilation unit with an operating range of 90–150 m³/h. The unit is designed for installation above a stove in the kitchen or as a cabinet-type solution in entryways, bathrooms, or other spaces. Thanks to its very compact design, the KS3 can be installed between kitchen cabinets and walls, hidden behind a kitchen cabinet door, or used with a Flexit design door.

The unit operates very quietly and uses a high-efficiency rotary heat exchanger for effective heat recovery. The fans have low energy consumption, making it an energy-efficient solution for smaller apartments and homes.

By default, the unit is controlled via the Flexit GO app, and optional accessories such as a control panel or CO₂ sensor can be added. The automation supports demand-controlled ventilation, improving energy efficiency and comfort. In case of high humidity, a defrost function activates to ensure reliable operation even in cold conditions.

• Built-in humidity sensor

• Condensation-resistant duct connections
